On June 4 episode of KBS' television show 'Family World Tour', the four members of Forestella―Ko Woorim, Kang Hyung-ho, Bae Doo-hoon and Cho Min-gyu made a guest appearance.
While on the topic of marriage, they brought up Ko Woorim's wedding to the hosts, "It still felt unreal on the day of Woorim's wedding. We were all like, 'Is this happening for real?' It was really hard to believe."
Ko Woorim shyly laughed, then expressed his gratitude to them for keeping his relationship with Kim Yuna a secret until he officially made it public through the media.
"All of them were aware that I was seeing her. Almost from the beginning, actually. I truly thank them for making sure that I enjoyed my dates without drawing attention from the public, and helping me prepare my wedding."

He continued as if he had been meaning to reveal this story for a long time, "One day, Woorim suddenly pointed at his phone, and tapped it so that I could see the lock screen. There was a photo of his hands holding Kim Yuna's hands. That's how I got to know about the two. When I learned that him and Kim Yuna were together, I went, 'What?! Are you crazy?!'"
Ko Woorim explained why he chose to break the news to them that way, "I was just shy to say the words out aloud. Even by thinking about telling them, 'We're dating.', I would totally blush."
With sincerity, he added, "But yeah, thank you once again, guys. Thank you for keeping it to yourselves, and also coming to my wedding."


Then they started dating about a year later; they were together for about three years before they got married last October.
